Patented Mar. 2, 1943 UNITED STATES PA'E'EN'!" ()FFICE 4 Claims.

This invention aims to provide a structurally improved means for ejecting ash and unburned tobacco from the bowl of a pipe.

It is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction herein-after described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Fig. 10 is a bottom plan of the cup.

The letter P marks a smoking pipe, including a bowl I, a stem 2 and a mouthpiece 3 detachably assembled with the stem, although the pipe may be fashioned as desired.

The bowl I is provided with a tobacco chamber 4. A threaded recess 5 is formed in the bowl I, at the lower end of the tobacco chamber 4, the recess being of a diameter which is appreciably less than the diameter of the tobacco chamber. The recess 5 has a reduced extension 6, communicating with a rectangularly disposed bore 1, the bore being in communication with a groove 8 extended lengthwise of the stem 2 and, if desired, opening through the rear end of the stem, adjacent to the mouthpiece 3.

A metal cup I0 is threaded into the recess 5 and has a reduced neck I I received in the extension 6 of the recess 5. The neck II is provided with a rectangular bore [2 which is open at its rear, as shown in Fig. 10. The bottom of the cup [0 is supplied with a lug l4 having a rounded surface l5. The bottom of the cup I0 is equipped with an upstanding hub [6, having a downwardly and outwardly sloping surface 11.

The numeral l8 marks an ejector disk, normally housed in the cup Ill, but adapted to be raised in the bowl I, for the ejection of ash and unburned tobacco. The ejector disk I8 is of considerably less diameter than the tobacco chamber 4, but a practically satisfactory removal of the ash and unburned tobacco will be eflected, and the disk is not intended to function as a bowl scraper. The disk I8 preferably is made of bri-ar,

or other pipe material, and since the cup In is made of metal, the parts l8 and 10 will not be cemented together by tobacco tar, around the edge of the ejector disk. The hub I6 spaces the lower surface of the disk is from the bottom of the cup l0, and the lower surf-ace of the disk will not be cemented to the bottom of the cup by tobacco tar. The lower surface of the disk I8 is downwardly convexed, as shown at l9. Owing to the convexity of the disk, as indicated at l9, and because the hub 16 has the downwardly and outwardly sloping surf-ace '11, the disk, as it moves downwardly to the position of Fig. 4, will tend to force the tobacco tar outwardly, in a radial direction, thereby keeping the bore I2 of the neck ll reasonably clean, so that an operating means (hereinafter described) for the disk I8, can work smoothly.

The operating means for the ejector disk 3 comprises a coiled spring 20, having its upper end mounted in the ejector disk, the spring being adapted to slide over the rounded surface l5 of the lug I4. The coiled spring 20 extends backwardly through the bore 7, and into the groove 8. The bore 1 is a trifle larger in diameter'than the spring 20, so that the spring can work freely" cause the bore l2 in the neck I I of the cup I0 is rectangular, the spring 20 has a minimum amount of contact with the neck, thus the spring is received closely, yet slidably, in the bore.

The numeral 22 designates a guide plate, pro-' vided at its forward end with the aforesaid hook 23, which engages in the bore 1, to hold the forward part of the guide plate assembled with the pipe P. The guide plate 22 is supplied with upstanding flanges 24, received in the groove 8. The flanges 24 are extended beyond the rear end of the guide plate 22, to form fingers 25. The guide plate 22 is supplied along its longitudinal edges with tracks 26.

of the guide plate is held detachably assembled with the pipe.

The edges of a slide plate 3| are mounted for reciprocation in the tracks 26 of the guide plate 22. The lower surface of the slide. plate 3| is flush with the lower surfaces of the tracks 26 on the guide plate 22, and, consequently, the pipe will stand securely on a desk, table or the like, with the bowl l upright. The spring portion 29 of the operating member for the ejector disk it passes backwardly, in sliding contact with the hook 23 of the guide plate 22, between the flanges 2 1 of the guide plate.

In order that the slide plate 3| may be manipulated readily, it is provided on its lower sur faces with a roughened portion 32, wherewith the thumb or finger of an operator may be engaged. At its rear end, the slide plate 3| is equipped with a reduced, overhanging neck 33, from which a holding prong 34 is struck, to define an opening 35. The neck 33 is equipped with oppositely disposed flanges 36.

The spring portion 2%] of the operating member extends between the flanges 35 and abuts at its rear end against the forward part of the neck 33. The forward part of the neck 33 has an opening The flexible element 2|, that forms part of the operating member, has its rear end extended through the openings 3? and 35, the prong 34 being bent down to grip the flexible element, as shown in Fig. 4. The forward end of the flexible element 2| passes upwardly through the ejector disk l8, and carries a button 38, engaging the upper surface of the ejector. The flanges 36 may be bent to grip the spring 20, or they merely receive the rear end of the spring without gripping it and for a purpose to be explained hereinafter. It will be noted that the flexible element 2| holds the convolutions of the spring tightly together,

even where the spring is bent, and the spring,

therefore, becomes an unusually effective thrust member.

The operation of the device is simple. The slide plate 3| advances the spring 20, the ejector disk I8 is raised, and the unburned "tobacco and the ash are discharged from the chamber '4 of the pipe bowl I. When the slide plate 3| is retracted, the flexible element 2| moves the ejector disk l8 down on hub l6, as in Fig. 4, without stretching the spring 20. v

Occasionally, it may be necessary to clean out the cup H]. In most instances this can be done by raising the disk l8 to full height and working around the edge of the disk with a knife blade, match or other tool, it being noted that the diameter of the ejector disk is considerably less than the diameter of "the tobacco chamber 4. The entire structure can be taken down for cleaning, whenever necessary.

All that the operator has to do is to take out the screw 30, thereby releasing the anchor '21 from the fingers of the slide plate 3|, the prong 34 of the slide plate 3| being freed from the flexible element 2|. If the flanges 36 of Fig. 8 have been bent to engage the spring member 20, they must be freed from the spring member: but if the flanges have not been bent to engage the spring member, the step last mentioned need not be resorted to.

The flexible element 2| holds all of the convolutions of the spring 20 in contact with each other. The spring 20 forms a longitudinally rigid thrust member, and the flexible element 2| constitutes a pull member,

Having thus described the invention, what is claimed is:

1. A smoking pipe comprising a stem having a longitudinal groove, an anchor comprising a body and a bracket extended into the groove; means for securing the anchor detacha'bly to the stem, a guide member having flanges extended into the groove, the flanges being prolonged beyond one end of the guide member to form fingers straddling the bracket and engaged above the body of the anchor, a releasable connection between the opposite end of the guide member and the stem, a slide mounted to reciprocate on the guide member, and means for connecting the slide cperatively with an ash ejector.

2. A smoking pipe comprising a bowl, and a stem having a longitudinal groove, an ejector mounted to move in the bowl, a slide, means for mounting the slide for reciprocation on the stem, the slide being provided at its rear end with a neck extended into the groove and ineluding front and rear walls, the front wall having an opening, a holding member struck from the rear wall and forming an opening therein, a coiled spring disposed in the groove and having its convolutions in contact, one end portion of the spring being assembled with the ejector, and the opposite end portion of the spring being assembled with the neck, and a flexible element extended through the spring, one end portion of the flexible element being connected to the ejector, the opposite end portion of the flexible element being extended through both openings of the neck and being engaged by the holding member.

3. A smoking pipe comprising a bowl and a stem, an ejector movable in the bowl, a slide mounted to reciprocate on the stem, a coiled spring extended between the slide and the ejector, and a flexible element extended through the convolutions of the spring and connected to the slide and to the ejector, the flexible element holding all of the convolutions of the spring in contact with each other, whereby the spring will constitute a longitudinally rigid thrust member, the flexible elementconstituting a pull member.
